HOISTING APPARATUS FOR RAISING SUNKEN LOGS AND THE LIKE;

Specification of Letters Patent.

Patented Feb. 14;, 1922.

Application filed December 26, 1919. Serial No. 347,497.

lie upon or are embedded in the bottom oflakes and rivers, there being certain lakes and streams where lumbering operations were formerly conducted which contain a great many such logs.

Second, to provide an improved holstmg apparatus by means of whlch sunken logs may be quickly and conveniently raised andv transported to shallow water from which they may be lightered or otherwise removed to a mill.

Further objects, and objects relating to structural details, will definitely appear from the detailed description to follow.

I accomplish the objects of my invention by the devices and means described in the The invention is clearly defined and pointed out in the claims.

A structure which is a preferred embodiment of my invention is clearly illustrated in the accompanying drawing forming a part of this specification, in which: 7

Fig. I is a plan View of a structure embodying the features of my invention, va-

rious parts being shown conventionally, certain parts being broken away and other parts omitted for convenience in illustration.

I1 ig. II is a front view with parts being broken away and other parts omitted and shown conventionally for convenience in illustration.

In the drawing similar reference characters refer to similar parts throughout the several views.

Referring to the drawing, I provide a pair of scows 1, ,1 rigidly connected a spaced relation by means of the cross beams 2 and the platform 3 to provide a space at between them so that a log or other object may be raised between them and towed or carried along in that aosition.

I provide paddle w eels 5-5 disposed at suitable sprockets.

the outer side of each scow. These paddle wheels are protected by the side rails 6, the platform 3 being extended to these rails. The paddle'wheels' are preferably arranged so thattheir lower edges do not extend below the bottoms of the scows, the scows thus serving as protecting means therefor. The rails 6 conyerge toward each end and serve as buffers for the scows. Housings 7 are provided for the paddle wheels.

The engine 8 is shown conventionally as of the internal combustion type. The driving shaft 9 is mounted to extend transversely across the space 4: between the scows, it be ing made up of sections connected by clutches 10 and 11, the clutches being shown conventionally. These clutches'lO and 11, generally known as marine clutches, also serve as a reversing means. The engine is connected to the intermediate section 12 of the driving shaft between the clutches by means of the chain 13 and suitable sprockets.

The hoisting drum shaft 1 1 is mounted transversely of the scows to extend across the hoisting space. The winding drum 15 is centrally located above this space. This winding drum shaft has a section 16 connected to the section on which the drum 15 is mounted,

by means of the clutch 17 and to the driving shaft by means of the sprocket chain 18 and The clutch '17 as illustrated is of the cone friction type. A friction clutch in this relation is of great advantage in handling the log. One of the paddle wheels is connected to the drum shaftby means of the clutch 19 while the other paddle wheel is connected to the driving shaft by means of the sprocket chain and suitable sprockets. The hoisting drum shaft is pro vided with a ratchet wheel 21 and a coacting dog 22 having a foot piece 23 by means of which the ratchet maybe released to allow free running of the drum as in paying out the hoisting cable 2e when the clutch. 17 is released.

The parts are shown mainly in conven tional form as the structural details may be greatly varied. I preferably use in this connection the logging grapples shown in my application for etters Patent filed concurrently herewith or that shown in Letters Patent No. 1,266,650, issued to me May 21, 1918. The inner sides of the scows areinwardly inclined at 25 so that'in hoisting a log it is not likely to catch on the bottoms of the scows and thereby injure the same.

With my improved hoisting apparatus, logs embedded in rivers and streams may be quickly and economically raised and transported to shallow water from which they may be removed by lighters or drawn upon the land or otherwise as desired. The paddle wheels may be driven independently or simultaneously so that the scows may be manipulated to the best of advantage in raising and also in depositing the logs.

I have illustrated and described my improvements in the form in which I have embodied the same in practice. I have not attempted to illustrate or describe certain adaptations and modifications which I contemplate, as I believe the disclosure made will enable those skilled in the art to which my invention relates to embody or adapt the same as may be'desired.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is: a a i 1.
